Service was personal and prompt. I had to exchange an item I incorrectly order and they were very accommodating and friendly. I plan to use them again.

An excellent parallel bar, replacing a forty year old bar. Easy to install. Good value.

The 60” parallel ruler was easy to install and works great. It is a professional tool. Very impressed.

Quality built instrument and was easy to install. I am pleased with my purchase.

Nice quality and smooth rolllers. But if using drafting dots to secure your drawing, be careful to lift up the parallel rule away the drafting board each time when sliding up and down. Otherwise, the low stance of the bar's top plastic edge, will catch the edge of the drafting dots and "roll them up" and off of your drawing.
